Abstract Background: Hereditary non-polyposis colorectal cancer is the most common cause of early onset of hereditary colorectal cancer. In the majority of Hereditary non-polyposis colorectal cancer families, microsatellite instability and germline mutation in one of the DNA mismatch repair genes in clouding MSH2, MLH1, MSH6 and PMS2 are found. The Objective of this study was to determine th...
متن کاملThe role of hPMS1 and hPMS2 in predisposing to colorectal cancer.
Hereditary nonpolyposis colorectal cancer (HNPCC) is attributable to a deficiency of mismatch repair. Inactivation of DNA mismatch repair underlies the genesis of microsatellite instability in colorectal cancer. Germline mutations in three DNA mismatch repair genes, hMSH2, hMLH1, and hMSH6, have been found to segregate in HNPCC and HNPCC-like families. The two DNA mismatch repair genes hPMS1 an...
متن کامل[Hereditary non-polyposis colorectal cancer (HNPCC)].
Hereditary non-polyposis colorectal cancer (HNPCC) is a type of hereditary colorectal cancer with autosomal dominant traits. Its causal genes are mismatch repair genes such as the hMSH2 and hMLH1 genes. Owing to its frequency, juvenile onset, and the outbreaks of multiple colorectal cancers and cancers occurring over multiple organs, it is recognized as a very important disease for the purpose ...
متن کاملHereditary Nonpolyposis Colorectal Cancer (HNPCC)/Lynch Syndrome: Surveillance and Diagnostic strategies
Introduction: Hereditary nonpolyposis colorectal cancer (HNPCC, Lynch syndrome) is an autosomal dominant genetic disease. The disease is caused by a mutation in one of four genes of the DNA mismatch repair system and increases the risk for various cancers, especially the uterine and colon cancers. The prevalence of this disease in the general population is about 1 in 500 and it causes about 2-3...
متن کاملMutations in DNA mismatch repair genes are not responsible for microsatellite instability in most sporadic endometrial carcinomas.
Endometrial carcinoma is the second most common tumor type in women with hereditary nonpolyposis colorectal carcinoma. Microsatellite instability (MI) has been observed in the inherited (hereditary nonpolyposis colorectal carcinoma-associated) form of endometrial carcinoma as well as in approximately 20% of presumably sporadic cases. Recent studies suggest that MI in many cell lines or xenograf...
